If x = − 6, which number line shows the value of |x|? A number line is shown from negative 6 to positive 6 with increments of 1. All the numbers are labeled on the number line. A dot is shown on a point at 6 tick marks to the left of 0. Above the number line, a bracket is shown extending from a point at 6 tick marks to the left of zero to 0. A horizontal line is shown between the brackets, and negative 6 is written on the line.
